VRENCH.

Application filed March 15, 1924.-. Serial No. 699,435.

To ZZ 107mm it may concern Be it known that I, JAMES M. CRooKnn, a citizen ot' the United States, residing at rlerre Haute, in the county of Vigo and State ot Indiana, have invented a new and useful llrench, of which the following is a specification.

This invention relates to tools and more particularly to monkey wrenches, the primary object ot the invention being to provide a monkey wrench wherein the movable jaw thereoit' may be readily and easily adjusted to adapt the wrench for use in connection with nuts of various sizes.

Another important object of the invention lte provide a wrench of this character which will be securely held in its positions of adjustment against movement while in use.

W' ith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details oi' construction hereinafter described and claimed, it being understood that changes in the precise embodiment ot the invcntion herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

teiferring to the drawing:

Figure 1 is a side elevational view of wrench constructed in accordance with the invention,

Fig. 2 is a iront elevational view thereof,

Fig. 3 is a sectional View taken on line 3*-3 of Fig. 1, and

Fig. 4l is a sectional view taken on line #1H-4f of Fig. 1.

Referring to the dra-wing in detail, the reference character 5V designates the handle portion of the wrench which is formed with an integral jaw 6 at its outer end,

',leeth 'T are formed integral with one edge et' the handle portion and are designed to cooperate with the teeth 8 of the movable securing member 9 that is pivotally supported within a out out portion of the movable jaw section 10.

lhc securing member 9 is formed with a flattened side portion 11 which when moved to a position opposite to the teeth 7 will allow the member 9 to clear the teeth permitting sliding movement of the jaw on the handle portion 5 of the wrench.

In order that the securing member 9 may be conveniently operated, the extension 12 is formed integral therewith, which eXtension normally engages one portion of the sliding' jaw 1() the construction of the extension 12 being such as to conform to the curvature ot the movable jaw 10 to lie out of the way of the user.

As shown more clearly by Fie. 3 of the drawing, the member 9 is formed with a flattened surface 13 adapted to be engaged by the spring member 14 that is secured to the movable jaw 10 so that the securing member 9 will be normally held in a position to lock the movable jaw against movement.

F rom the foregoing it will be obvious that when it is desired to make an adjustment, it is only necessary to move the extension 12 to a position at right angles to the showing in Fig. 3, thereby bringing the flattened side portion ot the securing member opposite to the teeth 7 permitting a sliding movement of the movable jaw to accomplish the adjustment thereof.

It might be further stated that due to this construction, the teeth 7 may be disposed in horizontal relation parallel withthe upper and lower edges of the wrench avoiding inclined teeth, which permit of movement ot the securing device when pressure is brought to bear on the usual wrench construction.

I claim zl A wrench comprising a handle portion having a jaw at one end thereof, said handle portion having teeth, a movable jaw adapted to operate over the handle portion, a securing member having teeth `formed along one of its edges and mounted eccentrically in the movable jaw, said securing member having liattened side surfaces and a flattened end surface, a Hat spring member secured to the movable liaw and adapted to engage the flattened end surface to hold the securing member in its active position, said spring adapted to engage one of the flattened side surifaces to hold the seeming member in its inactive position, and an extension formed integral with the securing member to operate the securing member.

In testimony that I claim the foregoing as my own, I have hereto ailiXed my signature in the presence of two witnesses.
